Accepting map submissions.

Hello. I registered on the site a long time ago, but for various reasons, I haven't visited it. Recently, I bought Heroes 5 and completed all the standard maps, but I got bored. I came to your site to look for maps. However, I haven't found any "challenging" maps yet. In those maps, the lands are represented as flat roads, with clear boundaries in the form of walls and garrisons. Basically, like in the dungeons of the Dwarves and the capitals of Haven. Have such maps been made before? And if not, has anyone had the idea to create something similar?
